Description

The present invention relates to a machine for processing wooden pieces provided with a mobile interface device.
The present invention also relates to a mobile interface device, in particular to a mobile device by land or by air.
The present invention also relates to a system comprising said machine and device.
More specifically, the invention relates to a machine for working workpieces made of wood, glass, fiberglass, ceramic, plastic, metal, provided with a mobile interface device of the above type, designed and realized in particular to provide information to an operator regarding the machine operating status, but which can be used for any operator interface function.
In particular, the mobile interface device can be a ground-based mobile device, such as a rover bot, or an air moving mobile device, such as a drone.
In the following, the description will be addressed to a machine for machining wooden workpieces but it is very clear that it should not be considered limited to this specific use.
As is currently well known, a woodworking machine is equipped with a fixed control unit usually located on the machine, through which an operator can interact with the machine, modifying its operating parameters also based on the machining state of the machine and of the expendable materials it uses for operating.
Known machines, therefore, force an operator to be always near the machine and the control unit, in order to intervene promptly in the event of sudden failures or malfunctions, or in the event of the need to replace expendable materials.
Alternatively, devices that can be worn by an operator are known, such as augmented reality glasses, connected to the machines, on which data relating to the operation of the machine are projected, coming from the service center of the machine, also providing information to the operator about any faults or malfunctions.
However, these devices turn out to be an unwanted encumbrance for the operators as they are forced to wear them during the entire working time.
The relevant prior art includes also the patent applications US 2017/343966 A1 , KR 101 257 275 B , DE 20 2016 106352 , and DE 102014209009 A1 . US10046429B2 discloses the preamble of claim 1.
